77.5 mpg US = 3.0 L / 100 km. [And the gauge actually reads a few % low since I'm running larger than stock diameter tires.]
[Or in other words, a bad day for you Honda Insight owners.
]
This was from a ~40 km round trip last night to go pick up a second hand floor jack.
Much pulse & glide silliness was used on the deserted and slightly rolling back roads [pulse up, glide down] that made up about 90% of the route. Alternator was also off, but that's less of a benefit in P&G than it is when just driving with load.
The outbound leg was actually over 80 MPG [tail wind].
